Nextant Aerospace received FAA STC approval for the 400XT–the model name for its remanufactured Beechjet 400A/Hawker 400XP–yesterday. The $3.9 million 400XT base package includes acquisition of the used aircraft and installation of new Williams International FJ44-3AP engines, Rockwell Collins Pro Line 21 avionics, new paint and an updated interior. It plans to deliver the first customer 400XT on Monday at the NBAA Convention in Las Vegas. Nextant will also have four of the remanufactured aircraft at the show–one at its booth, one on static display at Henderson Executive Airport and two at Flight Options’ McCarran Airport facility for demonstration flights. The company is working with Winglet Technologies to develop winglets for the 400XT that would be similar in appearance to those developed for the Cessna Citation X. Meanwhile, Nextant has begun to study its next aircraft for conversion, and company president James Miller told AIN that the chosen model would be bigger than the 400XT.
